.T his invention relates generally to shingles of the composition typeand more partlcularly relates to the provision of suitable anchoring construction for shingles of this general type.

Shingles of this type are usually laid in a diagonal position, that is, with the corners of a substantially square'shingle extendlng in horizontal and vertical directions `so that l. the lower portion of the shingle which is exposed to the weather is bounded b downwardly converging lateral edges. to anchor the lowermost corners of such shingles to the underlying shingles, it has been the practice to fold the corner .of the shingle to lie underneath the body portion and to thread through or secure to the underturned portion a separately formed bar or strip of 'metal or other suitable material having projecting ends.

A general object of the present invention is to provide a shingle having an anchoring device consisting of a single mtegral under` turned corner or tab member which affords laterall extending wing portions or edges adapted7 to perform theffunction of interlocking with adjacent shingles so as to hold the downward end of the shingle in place. Another object of the invention is to pro vide a. shingle of the interlocking type in which a square shingle blank is used without waste, and yet the bent under tab isl arran ed to interlock with adjacent shingles. e invention consists of a shingle provided with an underturned corner tab member bent on a line of fold which does not extend wholly across the shingle butterminates at each end ,at oints spaced from the lateral edges of the s ingle. This provides a tab member having an intermediate portion of eater width than theportion at the line of gld-and, in addition, 'provides downwardly projecting tip members in the body ofthe shingle at each end of the line of fold of the corner tab member. With this arrangement the downwardly extending and laterally separated tip members referred to extend along the edge portions of the adjacent underlying shingles and serve as 1de members in the placing of each shing e in proper superposed relatlon to the underlying shingles. Other useful results of this constructionl reside in the elimination of horizontal edge portions in the uppermost shingles which extend laterally from the inclined n order edges of the underlying shingles and provide a way for wind driven rain to find 1ts way beneath the shingles. Also the presence of the tip' members tends to resist wind forces in that the pointed terminals ofthe tip members cannot readily be engaged'and lifted by wind so that a secure and impervious roof construction is thereby rovided.

In the drawings, in w ich a preferred embodiment of the invention has been selected for illustration,

Figure 1 is a plan View ofva shingle embodymg the invention and showin a corner tab portion before it has been fo ded.

Flgure 2 is a view similar to Fi re 1 showing the corner tab portion of the s ingle in 'its underturned position.

Figure 3 is a view taken in line 3 3 of Figure 2.

Figure 4 is a plan or face view of a grou of shingles, such as is shown in Figure in assembling relation on a roof, or the like. l

Figure 5 is` a fragmentary view showing a modified form of the invention.

Referring to the drawings for a more detailed description of the invention, a shingle 10 is shown'which has a -substantiall square outline and is formed of any suita lecomposition, such as asphaltum-impre ated fibrous material. Such shingles are c aracterized by a certain degreeI l0f Aflexibility which renders it desirable to provide for securel anchoring the lowermost mar in of the sliin les beneath the edges of a jacent previou y laid shingles. It is the usual ractice to lay shingles of this type in' a iagonal position, that is, with the corners extending horizontally and vertically, the lowermost corner being arranged to support an anchoring device or to itself. provide an underturned anchoring tab member.

In the present invention a pair of short cuts or slits 11 are formed 1n oppositely disposed relation in the opposite edges ofthe section along shingle adjacent to the lowermost corner 10o portion 12.` The slits .1p1 are vformed substantially at ri ht angles or rpendicularly to the side,e ges o f the s ingle and the intervenin corner tab portion 12 is then bent underneatl 13 extending between and connecting the inner extremities of the slits 11.

With this arrangement it will be seen that l.

`a tab member 12 is formed' and which has laterally extending wing portions/14 which 110 the shinglealong the linevof fold usv tending tip portions resides in the resistplaced in servein practice to be placed in anchoring position beneath the edges of adjacent shintremities of theshingles. It Lwill be .seen that the fitting of these angular tip members to the angularly disposed edges of the adjathe shingle by wind forces tending to gles 10, as is clearly shown in Figure 4 of the drawing. f cent shingles 10 automatically brings about Not only is a desirable anchoring device the correct placement yor positioning ofthe thus provided which can be placed in inter- /shingle whereb the spacing nr alinement of locking engagement with two underlying" the shingles wlth relation to each other 'is shingles, but thev placing of the slits 11 invariably accomplished.

In order to secure the shingles in place in the position and in the direction shown provides a pair of downwardly extending the nails 16 may be made use of, preferably tip members 15 on the body portion of the two nails being used adjacent each lower shingle and at the opposite extremities of the ed e of each shingle. It will be seen that the line of bend 13- on which the tab member 12 nails are not driven throu is folded. The tip members l5 provide a bers, the object of this eing to permit number of useful functions in that they exlimited play or movement ofthe lower tab tend along upper surfacesA of the marginal portions of the shingles to obviate the tendpo'rtions of the adjacent underlying shingles ency to buckle which would be produced un- 10 and thereby obviate a horizontal edge der the expansion of the main body of the which has heretofore been presented 1n shingle by the action of the heat of summer shingles heretofore known., and used and temperatures. v. o which has afforded a means of entry for rain In a modified form of the invention shown driven by wind to ind its way back of the in Figure 5 of the 'drawing the pointed tip line of fold of the underturned tab mem on theend of the tab member is dispensed bers heretofore used. j

In covering the surfaces with shingles of 2.
